METALLIC SEAL.

SPECIFICATION forming part of Letters Patent No. 295,346, dated March 18, 1884:.

Application led January 16, 1884. (No model.)

.To @ZZ whom t6 inlay concern:

Be it known that l, EDWARD J. BROOKS, a citizen ol' the United States, residing at East Orange, in the State of New Jersey, haveinvented a new and useful Improvement in Metallic Seals, of which the following is a specilication.

This invention relatesr to improvements in those metallic seals composed, partly, ofsoft metal-lead being commonlyv used-and partly of `tin or'other sheet metal. Various forms of Vthese seals are shown in United States patents already granted for my inventions-wiz., No. 17 3,7 22, dated June 13, 1876; No. 209,008, dated October 15, 1878; No. 246,068, dated August 23, 1881; No. 254,601, dated March 7 1882,; No. 258,278, dated May 23, 1882; No.

, 260,279, cared June 27,1882, and No. 286,775,

dated October 16, 1883.

My present invention is more particularly in continuation of my series of inventions re lating to what I terni cast-in77 seals. A seal of this description is shown in said Patent No. 178,722 at Fig. 2l; and the advantages of the peculiarity are set 'forth in said Patents No. 246,063, No. 260,279, and No. 286,775, which relate exclusively to lead-andtm seals of this casein class.

The present invention consists in certain novel combinations, of peculiarlyconstructed parts, in a metallic sealv of soft metal and sheet metal combined, as hereinafter described and claimed. lts objects are, irst, to render the seal secure against stripping, and to manifest the construction by which t-his is accomplished; secondly, to provide for readily and cheaply making the sheet-metal part of the same of common tin.

A sheet of drawings accompanies this specication as part thereof.

Figure l of these. drawings is an edge `View of a seal illustrating this invention, the same being shown straight or ila-t, as it leaves the factory and is carried by the sealer. Fig.

2 is alongitudinal section of the same threaded, as for pressing. Fig. 3 is a cross-section on the line 3 3, Fig. 2. Fig. 4 is a face view of the same as applied to apair of staples and pressed-T7 Figs. 4? and Y represent magnified sections of the pressed seal, taken, respecttin, (tin-plate.) indicated by T.

ively, on the lines .r x and 'y y, Fig. 4. Figs. 5 and 5X represent, respectively, an edge view and aface view of the main end of another seal straight, ill ustrating a modification of the same invention. Fig. G represents a longitudinal section of the saine threaded; and Fig. 7 is a face view thereof pressed.

Like letters of referen ceiudicate correspond ing parts in the several gures.

The two seals shown in the drawings are, in fact, two forms ol' one and the same seal. In either form this improved seal is composed of a soft-metal Apart, preferably of lead, indicated by L, and a sheet-metal part, preferably of The lead L is cast fast within a holder, a, formed in the strip T, near one extremity of the latter, and its protruding portion is provided with a threading hole, b, extending therethrough lengthwise of the strip, immediately in front of the plane of the strip end c, in which the lead is held. The opposite end of the strip, (marked ik) termed its threading end,7 is of contracted width, and is provided with arr anchoring projection, e, on its outer side'or face, and thus armed is admitted freely by said threadinghole at the threading operation, so as to locate said projection within the lead, as shown in Figs. 2, 3, and 6. The lead is further provided with a central detectiveaperture, f, in its top or face, which, after the seal is pressed, as shown in Figs. 4, 4"', et?, and 7, exposes said anchoring projection, so as to manifest the construction of the seal and aid to prevent counterfeiting; and, finally, the threading end of the strip is provided with gage-shoulders g, which, coming in contact with the lead in the act of threading the seal, facilitate locating said anchoring projection c exactly behind or in line with saiddet-ective aperture f, as shown` In either form the strip T is iirst formed complete by known methods, and the seal L is cast fast therein, with the aid of a suitablemold. The article is then` ready for shipment and use. It is packed and can ried straight, as aforesaid, and after passing it through a pair of staples, s s, Fig. 4, or applying it in any approved way to any car-door fastening or anything else that can be secured by such a seal, it is threaded, as illustrated by IOO Figs. 2, 3, and 6, and is then pressed, as illustrated by'Figs. 4, 4x, 4V, and 7, by means of a suitable seal-press. It may be simply fdattened to fasten the seal, said anchoring pro- 5 jection c being securely embedded in the lead, so as to pre-elude stripping, as shown in Fig. 4; but for greater security against counterfeiting the pressed lead is preferably pro vided with distinguishing press-marksm, which may be readily indented deeply in the soft leaden face of the seal, as indicated in Fig. 4"; and the strip is for the same purpose preferably provided, in course of manufacture, with marks n, printed, stenciled, or stamped on the tin with suitable Water-proof ink, or burned in or shellacked vto render them permanent, or With permanent marks o, Fig. 6, embossed or otherwise formedin the strip or in the back of the holder c in any approved Way.

lIn the preferred form (represented by Figs. l to 4Y, inclusive) the holder c and anchoring projection c are both formed by simple bending operations, at'lapting this form of the seal to be readily and cheaply made of common tin; and the escape of the lead laterally is guarded against by punching a hole, h, in that part of the strip which subsequently forms the holder a, this hole and the inwardly-project ing metal therefrom being filled and embraced by the lead, as shown, at the casting operation.

seals for different users to distinguish them, .and this applies also to the detective-apertures c.

In the-modification illustrated by Figs. 5 to 7,- inelusive, the holder a is ofbutton7 form, or may be compared to the flange end of a hollow-headed metallic cartridge-shell, and may be readily die-formed, like thela-tter. The anchoring projection e of this seal is correspondingly struck up in contrast with the bent-up projection of said preferred form.

Holes of different shapes may be formed inl Soft tin or annealed sheet-iron, or thin brass or copper, may preferably be used in making seals with such button-holders.

The press-marks m (shown in Fig. 7) are 4 P. M. 12,12,S3, N.Y., indicating sealed at New York December 12,1883, at 4 o clock, afternoon. Such stamped dating-marks are claimed by me in another specification, and form no part of my present invention. They may be stamped on the strip, if preferred, at the sealing operation.

The permanent marks ofrepresented in dot ted lines in Fig. 7) are U. S. 0., for United States Customs.

Having thus described my said improvement in metallic seals, I claim as my inventionl. rlhe combination, in'a metallic seal, of a sheet-metal strip having at or near one end a lead-holder integral therewith, and at its other extremity a threading end provided with an anchoring projection on its face, and a leaden part, cast fast Within said holder, and constructed with a threading-hole and a detective-aperture in its protruding face portion, substantially as herein specified, for the purposes set forth.

2. An improved metallic seal composed, as herein specified, of a sheet-metal strip having at or nea-r one end a lead-holder, and at its other extremity athreading end provided With an anchoring projection on. its face, and a leaden part, east fast Within said holder, and constructed with a threadinghole and a detective-aperture to receive said threading end and expose its anchoring projection after the seal is pressed, said holder and projection being formed by simple transverse blends, as shown, for the purpose set forth.
